Patented July 7, 1931 UNITED; STATES PATENT OFFICE RALPH W. EMERSON, OFEAST ORANGE, NEW JERSEY, ASSIGNOR TO GYRO BRUSH CO., OF EAST ORANGE, NEWJERSEY, A CORPORATION OF Il'EVVl` JERSEY WASHING AND SCRUBBING BRUSHApplication ledApril 17, 1928. Serial No. 270,598.

The present invention relates to Washing and scrubbing brushes adaptedparticularly for use in connection with the cleaning of automobiles, andis in the nature of an improvement upon the brushes of the type formingthe subject-matter of United States Letters Patent to .lesse R. Masser,dated April' 19, 1921, No. 1,375,102; or, in other words, relates tothat class of brushes which embrace .a stationary border brushsurrounding a rotary brush, with provision for directing the washingfluid, such as water, through a tubular handle or shank to the twobrushes.

In carrying out my invention it is my purpose to improve and simplifythe construction of this type of brush by the provision of means formore efliciently directing the water to the stationary and the rotarybrushes, and at the same time to eliminate water waste and, also theliability of water dripping, spilling or splashing upon the operatorduring the washing operatin, especially when the brush is held in avertical or elevatedv position. A

It is also myy purpose to improve the mechanical construction of thebrush by forming the chambered brush-head with integral water directingor deliecting means, so that the head and the deflecting means may bemade in a single casting or piece, thereby eliminating the expenseincident to manufacturing and attaching separate parts.

Another object of the invention is to form or cast the brushhead with acontinuous, un-

broken peripheral side wall or flange which is devoid of holes oropenings, soy that the leakage or dripping of water through the` wall isavoided. Y

Another object of the invention is to simplify and improve thearrangement. of the supply passages and the co-acting parts forsupplying the water from the tubular handle or shank to the brushes.

It is also my purpose to provide a brush which will embody the desiredfeatures of simplicity, effectiveness and durability, and which may bemanufactured and marketed at a relatively low cost.

With the above recited objects and others of a similar'nature in view,my invention consists in the construction, combination .and arrangementof parts set forth in and falling within the scope of the appendedclaims.

In the accompanying drawings Fig-1 is a detail top plan view of a brushembodying my invention with certain parts broken away and portions ofthe stationary or border brush omitted;

Fig. 2 is a vertical sectional view taken on the line 2 2 of Fig, 1;

Fig.` 3 is a bottom plan View showing the rotary brush in position inthe chambered brush-head, but with the border brush omitted; y

Fig. l is a view in side elevation showing the brush-head and the rotarybrush, but again omitting the border brush;

Fig. 5 is a view in side elevation of the rotary brush.

' Referring now to the accompanying drawings in detail the numeral 1indicates a tubular handle or shank which may be connected at its outerend 2 to a hose or other suitable source of water supply. This tubularhandle orshank is cast integral with and extends at an angle to the headH of the brush body. The lower end of the tubular handle is closed as at3, but the passage or water channel 4 leads from the shank to andthrough the top of the head H so that the water under pressure may passfrom the tubular handle through the head to the brush bristles, ashereinafter described. Y

As will be seen by reference to the drawings, the head H comprises acircular platelike casting or disk 5 formed with a depending peripheralor side wall 6, thus forming a chamberA in the head. This latter isformed with a series of pairs of spaced lugs 7 cast integral therewithand adapted to receive between thel same and to hold a wire ring orband'or othervsuitable means for attaching and securing the stationaryor border brush B tosuch outer peripheral wall, as clearly shown in Fig.2. Formed integral with the bottom edge of the peripheral wall 6 of thehead is'au inwardly extending, lateral, segmental water deflect-ing ordirecting lip 8,

which is located adjacent to the discharge end of the water channel 4,so that any Water issuing from the same and striking against the topsurface of this flange will be directed inward toward the revolvingbrush, with a tWotold advantage,-iirst, that the requisite supply ofwater will be supplied to the brush, and second, that the angular streamof water issuing from the channel in the head will be prevented by thisdetlecting plate from sprayingdor streaming outward beyond the brush heaCentrally of the top wall or plate ot the head I provide a bore 9 forthe passage of the bolt l0, the shank of which is threaded as at ll forthe reception ot the retaining nut l2. This bolt revolvably holds therotary brush R within the head and forms the spindle for such brush. Therotary brush R is in construction somewhat similar to that shown in theaforementioned patent to Masser No. 1,375,102, and embodies a rotor 13having peripherally and radially arranged angular blades, vanes orbuckets 14 with spaces or openings l5 therebetween, so that the water,ai'ter striking the buckets and performing the function of turning therotor, may flow or pass down between the blades or buckets to thebristles of the border or stationary brush B.

From the above description taken in connection with the accompanyingdrawings, the construction and operation of my improved brush will bereadily apparent.

The tubular handle or shank is connected with the water supply and thewater, under pressure, passing down through the handle, flows throughthe channel Ll `and impinges at an angle against the blades'or bucketsof the rotor, thus imparting a rotary motion to the latter, and thewater passing down through the spaces or openings between the vanes orbuckets, will meisten or wet the bristles of both the rotary brush andof the surrounding border or stationary brush. At the same time it willbe noted that the deflecting lip 8, extending inward from the continuousperipheral wall of the head, is located adjacent the discharge end otthe channel 4, so that the stream las it issues through the head will bedirected or deflected inward of the brush` head, and thereby not onlyproperly wet the brush bristles, but the water will be prevented tromspilling or spraying outward beyond the brush head. At the same timevthe continuous, 'unbroken nature of the peripheral wall will preventleakage or draining or dripping of water upon the operator, particularlywhen the brush is held in an elevated position. Owing to the restrictedcharacter of the channel or duct 4; for supplying water from the tubularhandle to the brushes, and its location with respect to such brushes,the possibility of an excess supply, with consequent flooding orVdripping of the brush is avoided.

While I have herein shown and described my brush as particularly adaptedfor use in washing automobiles, it will of course be understood that itis not limited in its particular application to this particular purpose,as it may be employed :tor washing, cleaning or scrubbing in anyconnection wherein its use will be' found advantageous `and desirable. I

While I have herein shown and described a preferred embodiment of myinvention, it is not to be understood as limited to all the precisedetails set forth by way of illustration, as modification and variationmay be made without departing from the spirit of the invention orexceeding the scope ot the appended claims. Y

That I claim is:

l. AA device of the class described compris.-

ing a tubular handle, a chainbered brushhead connected thereto andcomprisinga top portion and a continuous peripheral side wall, therebeing a water vsupply channel leading :trom the tubular handle throughthe top wall of the head, a water detlecting member extending laterallyinward from the peripheral wall of the head adjacent the discharge endof the channel, a border brush attached to the peripheral wall andsurrounding the brush-head, and a rotary .brush revolvably mountedwithin the chambered head.

2. A device of the class described comprising a tubular handle, achambered brush-head comprising a iat circular top portion and aperipheral sidewall, there being a water supply channel leading `tromthetubular handle through the top wall of the head, a water deflecting lipformed integral with and extending laterally inward from the peripheralwall of thehead adjacent the discharge end ot the channel, a border'brush attached to the peripheral wall and surrounding the brushhead, anda rotary brush having peripherally and radially arranged angular bladesrevolvably mounted within the head vand adapted to be impinged upon androtated by Water issuing from the delivery end of the supply channel. j
